TrueDelta Reviews the Seat Room and Comfort of the 2016 Lexus RX

2016 Lexus RX Seat Room and Comfort: Cons
YearComment
The Lexus RX has the roomiest back seat of the three, the Lincoln MKX the tightest. Very tall people will prefer the RX's. At 5-9, I'm not tall, and found the other two back seats much more comfortable, with higher, better shaped cushions providing better thigh support and seat backs that were not overly reclined. The RX's rear seat back felt overly reclined to me even in its most upright position. Since it adjusts, why didn't Lexus engineer it to adjust over a wider range? see full Lexus RX review
